Can I skip a step and come back to it?

Yes. Every step can be skipped, and so can the whole wizard. A skipped step never leaves a wrong number. It leaves a data health flag, which is a warning that something is missing. For example, the P&L says that marketing spend is incomplete. Or it says that some products have no cost. It never treats the missing amount as zero.

The wizard has up to four screens: connecting Shopify, the import, your ad accounts and a summary. Skip setup for now takes you straight to your dashboard. The import keeps running on its own either way, so leaving early loses nothing.

To come back, open the right page rather than the wizard. Ad accounts connect in Settings, under Integrations. Product costs go on the Products page. Shipping, packing and returns go on Logistics. Payment fees go on Transaction fees. Fixed costs go on Overhead. The Overview lists what is still missing under Needs your attention, each item with a link to the page that fixes it.

This is the rule behind the whole product. A missing cost is shown as missing, never assumed to be nothing. A margin worked out on missing data is worse than no margin at all.
